This liquid wormer contains the very safe ingredient fenbendazole. Panacur is very effective against roundworms and other intestinal parasites, yet is very kind and gentle on your pet. This makes it suitable to use on puppies and kittens from 2 weeks of age. It is just as effective in adult animals too. Can be dosed into the mouth, or mixed in food.

Each bottle comes complete with a plastic measuring cup for easy dose measuring.

(ii) Operator warnings:

Direct contact with the skin should be kept to a minimum.

Wear impermeable rubber gloves and wash hands after use.

(iii) Other:

The use of this product should be based on local epidemiological information about susceptibility of the nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

Adverse reactions

Gastrointestinal signs (such as vomiting and diarrhoea) can occur in very rare cases in the dogs and cats.

The frequency of adverse reaction is defined using the following convention:

Use during pregnancy, lactation or lay

The product can be used in pregnant bitches. As teratogenic effects in dogs and cats cannot be completely ruled out in very rare cases, the treatment in the first two trimesters of pregnancy should be based on the benefit-risk evaluation by the responsible veterinary surgeon.


None known.

Amounts to be administered and administration route

Shake the container before use.

Routine treatment of adult cats and dogs

1 ml per 1 kg body weight as a single oral dose (= 100 mg fenbendazole/kg body weight).

Practical dosage recommendations:

2 to 4 kg 4 ml
4 to 8 kg 8 ml
8 to 16 kg 16 ml
16 to 24 kg 24 ml
24 to 32 kg 32 ml
32 to 64 kg 64 ml

For dogs weighing over 64 kg, an extra 1 ml is required for each additional 1 kg body weight.

The dose should be mixed with feed, or administered orally directly after feeding.

Treatment should be repeated when natural reinfestation with parasitic worms occurs. Routine treatment of adult animals with minimal exposure to infection is advisable 2 to 4 times per year. More frequent treatment at 6 to 8 weekly intervals is advisable for dogs in kennels.

Puppies and kittens under six months of age

0.5 ml per kg body weight daily for 3 consecutive days given by mouth after feeding to unweaned animals or mixed with food for weaned animals (= 50 mg fenbendazole/kg body weight daily for 3 days).

Practical dosage recommendations:

Up to 1 kg 0.5 ml daily for 3 days
1 to 2 kg 1 ml daily for 3 days
2 to 4 kg 2 ml daily for 3 days
4 to 6 kg 3 ml daily for 3 days
6 to 8 kg 4 ml daily for 3 days
8 to 10 kg 5 ml daily for 3 days

For puppies weighing over 10 kg, an extra 0.5 ml is required daily for each additional kg body weight.

Puppies should be treated at 2 weeks of age, 5 weeks of age and again before leaving the breeders' premises.

Treatment may also be required at 8 and 12 weeks of age. Thereafter, frequency of treatment can be reduced unless the pups remain in kennels where reinfestation occurs more readily.

Pregnant dogs

1 ml per 4 kg body weight daily from day 40 of pregnancy continuously to 2 days post-whelping (approximately 25 days) (= 25 mg fenbendazole/kg body weight daily).

Practical dosage recommendations:

4 kg 1 ml daily for approx. 25 days
8 kg 2 ml daily for approx. 25 days
12 kg 3 ml daily for approx. 25 days
20 kg 5 ml daily for approx. 25 days
40 kg 10 ml daily for approx. 25 days

For dogs weighing over 40 kg, an extra 1 ml is required daily for each additional 4 kg body weight.

As treatment of pregnant dogs is 98% effective, puppies from these dogs should themselves be treated with a three day course at 2 and 5 weeks of age.

Pregnant cats

Pregnant cats can be safely treated with this product but only require a single treatment at the routine adult dose rate. Administer 1 ml per 1 kg body weight as a single dose (=100 mg fenbendazole/kg body weight).

Increased dosing for specific infections

For the treatment of clinical worm infestations in adult dogs and cats or Giardia spp. infections in dogs administer 1 ml per 2 kg body weight daily for 3 consecutive days (= 50 mg fenbendazole/kg body weight daily for 3 days).

Pharmacological particulars

Pharmacodynamic properties

ATC Vet Code: QP52AC13

Fenbendazole is an anthelmintic belonging to the benzimidazole carbamates group. It acts by interfering in the energy metabolism of the nematode. The anthelmintic efficacy is based on inhibition of the polymerisation of tubulin to microtubuli. The anthelmintic affects both adult and immature stages of gastro-intestinal and respiratory nematodes.

Pharmacokinetic properties

Fenbendazole is only partly absorbed after oral administration and is then metabolised in the liver. Fenbendazole and its metabolites are distributed throughout the body and high concentrations can be found in the liver. The elimination of fenbendazole and its metabolites occurs primarily via the faeces (>90%) and to a small extent in the urine and milk.

Fenbendazole is metabolised to its sulphoxide, then to sulphone and amines.

Q & A

Below are some recent questions we've received regarding Panacur Oral Suspension for Dogs & Cats, including answers from our team.

Panacur liquid

Lynette Ayres

  • VioVet customer since 2016
  • From: Gloucestershire, United Kingdom

How much would l give to a tiny dog about 6lb in weight

  • Veterinary Advisor

6lb is roughly 2.7kg so the practical dosage recommendation at this weight is 4mls at a single oral dose for routine treatment. It is advisable to repeat this around 4 times a year. However dosing is increased for specific infections such as control of lungworm which requires dosing at 1 ml per 2 kg bodyweight daily for 7 consecutive days.

8 August 2016 at 7:58pm



Please can you tell me how many ml each puppy needs at 2week, 5week and then 7weeks.

  • Brand Manager

Hi Rebecca,

The amount each puppy will need will depend on their weight, so you will need t o weigh each puppy before treatment, and give the appropriate ml per kg bodyweight.

The recommended dose is 0.5 ml per kg bodyweight daily for 3 consecutive days. If your puppies weigh 2kg at 2 weeks, they would need 1ml daily for three days.

Full dosage instructions will be included in the packaging, and can also be found on our website in the description tab below the listing. I hope this helps!

Safe to treat rats


Hi I just got 4 baby rats who need worming they have round bellya and looks as if their soft poop has white bits in is this product safe to treat them

  • Non-Executive Director

It is unusual for rats to need worming though this is possible. Strictly speaking since Panacur is licensed for use in dogs and cats, if you want to use it in rats, this decision should be taken by the vet who is in charge of their care. However Panacur is in fact a very safe wormer if given at the correct dose according to body weight.

How many doses

Louisa McKitten

  • VioVet customer since 2016
  • From: County durham, United Kingdom

I have been prescribed panacur 10% 0.4mg for my 3 year old horsfield tortoise. Im wondering if i have to repeat the treatment in 10 days or will this be a one off dose

  • Non-Executive Director

I wonder how you are going to administer this as it is not easy to stomach tube this species. Giving with food is not very reliable at all. Assuming you are successful, it is normally a one-off dose for routine worming. Some people advocate giving just one third of the dose daily for 3 days, to reduce the chances of toxicity to the tortoise and to increase the effectiveness of the worming dose. Most people do just give a single dose however. Ideally you should check with the vet who prescribed this.

Giardia Panacur Granules Panacur Oral Suspension/Liquid


  • VioVet customer since 2015
  • From: Cheshire, United Kingdom

Hi. Wondering if you can help me? I have a 40kgs GSD. What is the dose of Panacur Granules/Oral Suspension/Liquid to treat Guardia?

  • Non-Executive Director

For the treatment of Giardia spp. infections in dogs using 10% suspension, administer 1 ml per 2 kg bodyweight daily for 3 consecutive days (= 50 mg fenbendazole/kg bodyweight daily for 3 days).

For your dog this means 20mls per day for 3 days.

Panacur oral suspension

Sarah q

I was told today by my vet that this only works against lungworm in cats.! I understood it to be for dogs and cats! I'm confused

  • Non-Executive Director

In a way you are both correct. This is a very good wormer for many different species of animal, including dogs and cats. However it is not able to kill every type of worm in every species. In the cat it is effective against the usual cat lungworm, along with the worms which live in the gut. In the dog it is effective against the worms which live in the intestines and for one type of lungworm. However the lungworm which is the biggest concern for dogs and is in the news a bit at the moment is not effectively controlled by Panacur at all. A different wormer has to be used in dogs if this worm (Angiostrongylus vasorum) is a concern.

Lungworm treatment

Brenda Needham

My dog is regularly wormed with panacur,which I understand doesn't protect him from the lungworm passed on from slugs.He is a border collie and and I dont want to put advocate on him.
So if he ever picked this worm up,what would the treatment be.?
I have been told advocate is not safe on some breeds.So I do worry about the whole thing.Lungworm has affected a few dogs in the area.(Kent)

  • Non-Executive Director

The only product which is known to be effective against the type of lungworm you are concerned about is indeed Advocate. This belongs to a group of drugs which Collie types are known to be particularly sensitive to. However as long as you give Advocare at the recommended dose, it seems to be very safe for Collies and I would not worry about that, it is only a problem if they are accidentally over-dosed, which of course you should not do anyway.

15 January 2015 at 9:30am



Does it kill lungworm?

  • Non-Executive Director

The answer is yes and no. There are different types of lungworm and it is possible to kill them at different stages of their development, all of which have an impact. Panacur will kill the type of lungworm called scientifically Oslerus (or Filaroides ) osleri. However this lungworm is not a big deal in dogs and killing it is not hugely important. The type of lungworm in the news at the moment is a completely different creature. Called scientifically Angiostrongylus vasorum, it is NOT treated effectively by Panacur and you cannot rely on it to look after your dog regarding this lungworm. Therefore it is true to say that Panacur kills lungworm, but that is missing the point. It is not what you want. The most effective treatment appears to be the prescription product Advocate, which kills lots of parasites including, the lungworm you are probably asking about. Sometimes life is not simple!

Panacur for snakes

Ayoub Sayed

how much (ml or mm in the syring) panacur i have to give an adult rat snake and for how many days or for how long.

  • Non-Executive Director

You will need to know the weight of your snake first. Then if you are using the 10% Panacur suspension, you should give 0.5mls per kg bodyweight of snake. Repeat this in 2 weeks, then again 2 weeks later. If you use a 1ml syringe, then often these are graduated in one hundredths of a ml, so it would be the 50 mark on the syringe for a 1kg snake, or 1 unit on the syringe for every 10g of snake. If in doubt, you should talk to your vet about this. Unless we are given a prescription from your vet, as an online supplier we can only sell this product for use in dogs and cats due to licensing regulations. Your vet can prescribe it for reptiles and other animals.

Can treat for worms and Giardia at the same time?

Paul Glover

I have wormed my dog using Panacur but can I use Drontal for worms at the same time, or how long should I leave it?

  • Brand Manager

It should be OK to consider that what you have already given is a good worm dose already, so the next Drontal dose will not be needed for 3 months or so, depending on how often you treat for worms anyway.

(I assume you have given Panacur 10% so that 0.5mls would equate to 50mg of Panacur. The correct dose of Panacur for Giardia is 50mg/kg daily for at least 3 days. Some tapeworms are not controlled by Panacur, but they are not at all common in most parts of the UK. Other worms should be killed OK. Panacur at 50mg/kg for 3 days is very effective against most worms.)
